Application ledvFQaruary 20, 1882. (No model.)A

To all whom it may concern:

Beit known that l, HENRY MAECHETEE, ot' the village of Wallacebnrg, vinthe county ot' Kent, Province of Ontario and Dominion of Canada, haveinvented a certain new and useful Improvement in Cnr-Oonplers; and I dohereby declare that the following is a full, clear, and exactdescription of the construction and operation ot the same, referencebeing had to the accompanying drawings, in which e Figure lis a .sectionof the machine with. the side cap or lid removed from the box or block,showing the internal appearance before the link enters the mouth of themachine or coupler. Fig. 2 is also a section, the same t view showingthe change produced by the link K being pushed back into the machineorcoupler. Fig. 3 is likewise thesame section, showing the effect producedby lifting up the pin H. Fig. 4 is a perspective view of the shuttle orvalve Gr. Fig. 5 is also a perspective view ot' the Ilan ged shuttle orvalve J.

My improvement relates to machinesfor coupling railroad-,cars that willbe'self-fast eners.

The invention consists in the construction and arrangement vot' part-s,hereinafter more fully described and delinitely claimed.

A is a box or block ot' iron or other suitable material, and of propersize, fastened at the end of a car as desired, and the end ot' this boxor block is the part that strikes when the cars come together. B is thehorizontal entrance or mouth. C is a horizontal chamber to allow the endot' the link K to enter'. D is an inclined chamber running back and up.E is also an inclined chamber ruiming forward and up. F is aperpendicular hole, situated between the two chambers D and E, andrunning clean through the coupler, and in communication with all thechambers already mentioned, also is the hole in which the pin H works.Gr is aloose wedge-shaped valve or shuttle, working freely up and downtheinclined chamber D. His an ordina-ry pin, litting the hole F loosely,and long enough to extend well through the machine. J is another valveor shuttle, with lian ged sides, that works freely up and down theinclined chamber E. K is the link, that is properly adjusted to theother car, about to enter the mouth B, as seen in Fig. l. L is a smallchain, made last tothe piu H and to the body ot' the machine, and isadjusted not to allow the pin to be taken out altogether.

My machine operates as follows: 'llhe link K enters the mouth B andstrikes the shuttle G, upon which the pin H rests. The shuttle Grinstantly dies from upder the pin and goes up the chamber D, and the pinH falls through the link K, thus coupling the cars, as is seen in Fig.2., When it is desirable to uncouple the cars the pin H is drawn upward,and when drawn up above the chamber E the shuttle J slides under the pinand holds it up. Then when the cars move away from each otherthe linkcomes out ot' the coupler, and the link coming out lets the shuttle Grslip back to its original place, as is seen in Fig. 1, and at the sametime the link catches on the lower pendent part of the shuttle J andsends it dying up the chamber E, causing the pin H to fall back again ontop ot the shuttleGr toits original position, as seen in Fig. 1, and allready t again to couple itself when operated upon by the link as before.

It' desirable, the hanged shuttle J can be dispensed with, andthe carswill couple the same; but the pin would then have to be taken clean outwhen uncoupled, and when the link was out the pin would have to be putback again, so that it would rest on the shuttle G. It then would be inreadiness for self-couplin g.

Having thus described my invention, what I claim herein as new is- In acar-coupler, the combination of the chambers B, C, D, and E with theshuttles G and J, and their relation to each other as herein shown anddescribed.

In witness whereof I have hereunto signed my name, in the presence of`two subscribing witnesses, this 16th day of January, 1882.

HENRY MABGHETER.
